Well, this sucks (2)
Or, more precisely, it doesn't.
They argue it would take just two and a half years for vampires to wipe out the entire human race from the day the first one appeared, based on the myth that vampires turn their victims into other vampires by sucking their blood.
If vampires feed once a month, the great grandaddy of all vampires would have killed one human and produced one vampire in the first month. So in total there would be two vampires and one less human, or a tally of vampires 2, humans -1. By the next month, the 2 vampires would kill 2 humans, and so on.
After n months there would be 2 x 2 x 2 ... x 2 = 2n, or a geometric progression with ratio 2. "The vampire population increases geometrically and the human population decreases geometrically," they say.
Using the principle of reductio ad absurdum, they conclude that vampires can't exist as their existence contradicts the existence of humans.
